[0037] Working principle: When in use, the cutting device 2, conveying mechanism 3, distance control mechanism 4 and pressing mechanism 6 are set, wherein the pressing mechanism 6 includes a movable block 601, a U-shaped limit frame 602, a slider 603, a limit slide 604, a limit rod 605, a screw 606 and a pressing block 607. When in use, the bar material is placed on the conveying mechanism 3 for conveying. When the bar material needs to be cut, the conveying mechanism 3 stops running, and the driving motor 13 drives the cutting device 2 to move. When the protective shell 11 moves, it drives the U-shaped limit frame 602 to move, so that the slider 603 slides in the limit slide 604. When moving in the inclined groove, the movable block 601 moves down. When the slider 60 When the movable block 601 moves to the transverse groove, it moves down to the lowest position and will not move any further. At this time, the pressing block 607 squeezes the bar material to stabilize it. Under the push of the pushing motor 13, the cutting device 2 moves horizontally to cut the bar material. At the same time, the slider 603 moves in the transverse groove of the limiting slide groove 604.

The distance of the second mounting disk 408 is adjusted according to the length of the bar to be cut as needed. When the bar is conveyed, when the end hits the second mounting disk 408, the touch switch 407 is pressed. At this time, the conveying mechanism 3 stops working, and the driving motor 13 drives the cutting device 2 to move for cutting, thereby completing automation with a high degree of automation. The second mounting disk 408 presses the touch switch 407. Since the finger rod 409 is fixed at the fixed end of the touch switch 407, the distance between the finger rod 409 and the cutting wheel 12 minus the thickness of the second mounting disk 408 is the required length of the bar to be cut.
